i have an old Vectra VL420 Mt and on the past November it has failed on boot.
The first symptom was a problem with the graphic windows, where in the windows had disappeared the three icons in the upper right: closing, minimizing, icons magnification. So there were some lines that are not defined on the monitor. Then the next boot was interrupted.
I have checked in the "beep error codes" and my case is "Number of beeps emitted: 0 - without 'buzz' audio signal"; after the control of all cables correctly plugged i have thought that is the mainboard to by replace.
In details the problem is the follow:
- pressing the power button no audio signal e no drive detected (floppy drive, cd-rom drive, cd-burner drive, hard disk
drive) only light up the cooling fan (processor and case's fans) and the green LEDs on the PCI bus.
- pressing the power button more than 5 seconds, there is the buzz initial sequence and after no beep code, "0 beep".
- disconnecting the 2 data cables of cd drive and pressing the power button the drive were detected (excepted floppy
drive and hard drive) but no video signal with black screen.
I have checked the level of tension on power plug of the floppy drive and are present +5V and +12V but this drive are
not detected. I have changed with another floppy drive (properly functioning) but there is the same problem.
- i have changed the mainboard with another used, but remaining the same problem.
- Also after disconnecting (in succession) the video card, or the RAM, or all the disco drive remaining the problem.
- I have 2 other pc Vectra VL420 functioning properly and I would be tempted to try to disconnect / connect the
individual components but I'm afraid I do on these problems, so avoid it.
What could be the cause of the problem?

Hi, take a look at our step-by-step guide to troubleshooting startup problems:
Resolving Startup Problems
Hopefully this will help solve your problem, or at least get you pointed in the right direction to isolate the problem.

Ever tried replacing RAMS with newer ones?
If you refer to my post HP BRIO 8032 problems you see I had a pretty funny behaviour of my HP PC due to defective memory dimms.
The story sounded like yours.
